Classic FTP LIST directory traversal
| classicftp-list-directory-traversal (43230) |  Medium Risk |
Description:
Classic FTP could allow a remote attacker to traverse directories on the system, caused by an error in the FTP client. By persuading a victim to download a directory containing a file with "dot dot" sequences using forward-slash or backslash characters (../ or ..\) in the filename via the LIST command, an attacker could traverse directories and write arbitrary files to the system.
